Certainly websites allow the curious to find out more about the
subject in "the privacy of your own home", as the saying goes.  And
face it, we all are a little curious unless we've been there, done
that.

there is a nudist beach in Brighton UK - you should go there and ask them

Though there may not be many nude bathers at this cold, wet time of year.

You should read the ALESSANDRA'S SMILE, INC., court case.  It dose
wonders for the legal issues involved with naturism. The case concerns
264 nudist magazines that were imported to the United States from
France and Germany. The magazines, which are either in French or
German, are devoted to nudists' lifestyles. All of the magazines
contain numerous photographs of nude persons, including adult males
and females as well as nude minors and nude teenagers.

When court cases like this are won it sets a statue for citizens to
follow making social nudity more acceptable worldwide.  You might
consider contacting NudistLaw.com for more details.

I think much easy to ask about it real naturists and exhibitionist.
I had such question one time before and one girl helped me with it.
She is WebCam model and as she told about herself she is 'EXTREME
exhibitionist from the land of hot desires'.
Feel free to ask her about places  yourself.
